Worst flare since DX, struggling...

Hi guys, I'm new to this forum, I normally keep quiet and struggle to reach out so me being here says that I'm really struggling :(
Firstly, I live in Victoria, Australia, have had UC for approx. 10 years, I have had a few flare ups in the time, mostly controlled by pred but once requiring a couple nights in hospital... I take Imuran 100mg (but may have to increase)... What brings me here now? Normally my flares are consistent of bloody D and frequency, this time constipation for months, stools ranged from formed large amounts to tiny pebbles all with se blood, but always plenty of blood when cleaning.
Currently I am in hospital following 3 months of oral pred treatment that did not help. It is now day 5 of hospital, day 5 of 6 hourly cortisone doses through IV with not much response, sigmoid scope showed severe ulceration. Last night I was started on rectal meds (some form of large tablet and an enema) also started 3x Balsalside tablets with each meal. After sleeping for a few hours with the enema I had a large movement with barely any blood (which was a great deal of relief to me but short lived as I had another 3 movements in the next 3 hours of blood and unformed stool... Don't know what to make of it)
Docs here say diet/supplements have NOTHING to do with UC symptoms which I find outrageous and encourage me to eat "whatever I like" (which I don't, but honestly no idea what to avoid and what to have)
I am desperate for ANY improvement so that I can get home and maintain my own treatment. The HARDEST part about this is not symptoms... I am a single father to my 6 year old daughter, she is a very sensitive child and it has just been me and her for the last 4 years of her life. I am her rock, her everything and she cries everytime I see her, every time I speak to her and every time a visit is over because she doesn't understand why daddy can't come home, why she can't be home in her own environment. It's breaking my heart and I need to get home...

Hi, thanks for that reply, and whilst I appreciate it I still want to avoid surgery at all costs unless it's an absolute last resort...
I have never heard of remicade and humira and my docs have never mentioned either.
As I said this is by far my most severe flare since DX over 10 years ago and completely different to any other, the constipation is ridiculous... I have been on laxatives (weening down) and stool softners. I will mention a few other things whichever may or may not be helpful to further advice from the community...
I seem to be going to the toilet in the morning around 3 times in 3 hours and then not having to go at all until around dinner time where it's a similar pattern- one decent movement followed by 2-3 of broken up stool and some blood within the next couple of hours.
Again I am also very confused as to what foods/ supplements actually WILL help in some way (such as psyllium husk/flax seed oil) and what to avoid (dairy? Acidic foods like tomato pasta sauce etc)
Onion, garlic, chilli, pepper, yogurt, milk, chocolate, green veges, citrus fruits etc I'm all assuming should be avoided??
I know food isn't the be all and end all solution but whilst the bleed control is out if my hands medication wise, I'd like to assist as much as possible to stay out of hospital when I get out, my daughter needs me!

The enema is a good choice, although I'm sorry you haven't had this sooner. It takes more than one to make a difference. Most of us find the enemas do their job rather slowly (or, think of it another way - rectal inflammation is a beyotch). Consistent use over many weeks will hopefully provide the relief you need.

Hardly anybody ever dies from UC or it's treatments, not that there aren't any side effects.

Thanks for the input, I have an update today but I'm not sure what to think of it... They want to introduce me to the rescue remedy tomorrow, (Remicade/Infliximab) and then monitor me for a couple of days after that continuing oral pred, Balsalside and up my Imuran to 200mg.... How does this sound to you guys? How good is the Remicade?

So so sorry for your struggles!!

I saw a huge difference less than 24 hours after my first Remicade infusion. In my opinion, its worth it. My family calls it the miracle drug.

Absolutely. I have only had my first two doses so far, but remicade took me from watery bloody D to semi-formed no blood BMs. (semi-formed meaning it looks solid in the bowl and breaks up a bit when flushed). I have only had 2 doses so far, and there are 3 bolusing doses in the beginning to build the drug levels up in your body to a plateau, so I don't even have the full levels in my body yet. In the last couple weeks, I have noted that blood has returned every now and again and my GI prescribed me mesalamine enemas for this which are helping. My BMs have stayed semi-solid though.
